“…Shin et al 2002 andCooper andBidwell 2006, have evaluated the burial conduct (burial rate) of mollusks as a response to exposure to metals and pesticides present in sediment. Variations in valve opening and closing time are also considered to be responses to metal exposure (Hughes et al 1987;Inda and Cuturrufo 1999), but this response is not specific to toxic compounds since it is also provoked by factors such as temperature and low oxygen tension (Roger et al 1990;Borcherding 2006).…”

We conducted an evaluation of alterations produced in the valve closing speed of juvenile Argopecten ventricosus (Catarina scallop) exposed to the metals cadmium, chromium and lead, because of the connection of this response to the state of health of the mollusk. Bioassays were conducted with 50 juveniles (length 3 +/- 0.5 cm) exposed to 0.02, 0.1, 0.2 mg Cd l(-1); 0.1, 0.5, 1.0 mg Cr l(-1); 0.04, 0.2, 0.4 mg Pb l(-1) and 0.8 and 1.6 mg Cd + Cr + Pb l(-1) for 480 h. The average valve closing speed at the end of the experiment was under 1 s in the control group, from 2 to 3.6 s in the bioassays with cadmium, from 1.4 to 3.4 s with chromium, from 3 to 12 s with lead, and from 12 to 15 s with the metal mixtures. It was found that there are significant differences between the values recorded in assays with metals and the control (P < 0.05). The retardation of valve closing in the organisms exposed to toxic substances is probably caused by damage to the sensory cilia located on the edge of the mantle.

“…Although the role of BChE is obscure, distinctions between these two biomarkers of exposure could be useful as a component in toxicity identification evaluations (TIE). A contaminant avoidance experiment with a scallop (Argopecten purpuratus) by Inda and Cuturrufo (1999) Refractory organics decreased Cd-AE relative to carbon-cleaned sediment but not relative to high levels of EPS. Cd-AE increased with increasing gut passage time in worms not pre-exposed, while pre-exposure reversed this trend, and Cd-AE from humic acid coated particles was independent of gut passage time.…”

Papers reviewed herein are limited to the biological, chemical and physical effects of environmental disturbance, natural, and anthropogenic, on marine and estuarine plants and animals. The world wide literature is reviewed including textbooks, conference proceedings and reviews. A special feature is a tabular listing of the body burden of inorganic and organic contaminants in plants and animals. The effects of pollutants on individual species and communities are included. Changes at the cellular and subcellular level as caused by contaminants are reviewed. GENERAL Books and reviews on the different aspects of marine and estuarine pollution continued to appear during 1998-1999. A new series on current topics in ecotoxicology and environmental chemistry was initiated. The first volume was edited by Forbes (1998) and dealt with genetics and ecotoxicology. The role of genetics in understanding if and how chemical contaminants affect organisms and populations was stressed. The current status of the effects of pesticides on 15 tropical countries was summarized as a practical guide (Klaine, 1999). Guest editors Stebbing et al. (1998) assembled a series of studies on the integration of the interaction of rivers, estuaries, ocean and land in the United Kingdom with emphasis on the Humber Estuary. The reports emphasized three aspects: (1) to estimate the fluxes of sediment, nutrients and contaminants into and out of the coastal zone by rivers, coasts, ground water and atmosphere, (2) to determine the key physical and biogeochemical processes that govern coastal ecosystems, and (3) to describe the evolution of the coastal system from the geological past to the present using the Humber Estuary as a case study.

This review covers selected 2014 articles on the biological effects of pollutants and human physical disturbances on marine and estuarine plants, animals, ecosystems and habitats. The review, based largely on journal articles, covers field and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, dredging and disposal, etc. Special emphasis is placed on effects of oil spills and marine debris due in part to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and the 2011 Japanese tsunami. Several topical areas reviewed in the past (ballast water and ocean acidification) were dropped this year. The focus of this review is on effects, not pollutant fate and transport. There is considerable overlap across subject areas (e.g.some bioaccumulation papers may be cited in other topical categories). Please use keyword searching of the text to locate related but distributed papers. Use this review only as a guide and please consult the original papers before citing them.
